干旱、增温及其交互作用对植物生理的影响
Main and interactive effects of drought and warming on plant physiology
摘要
Abstract
The main and interactive effects of drought and high temperature stress on plant physiology remain uncertain,which limit our ability to predict accurately the plant responses to future climates.In this review,the effects of drought and high temperature on carbon exchange and water relations were discussed respectively.Drought stress usually results in higher xylem embolism,reduced growth and photosynthesis.Leaf photosynthesis is increased with rising temperature below the thermal optimum,while it declines once temperature is exceeded above the thermal optimum.Respiration often has higher thermal optimum than photosynthesis,thereby potentially leading to negative carbon balance on plants.Drought stress and high temperature are usually linked and therefore each stress exacerbates the other stress.Therefore,combined stress of drought and high temperature can pose significant threats on plant survival.To sum up,the interactive effects of drought and high temperature on plant physiology are needed to consider for predicting plant responses to future climates.关键词
